How to repair a bicycle hydraulic v-brakes. Bike service

Hello fellow cyclist. In this video, I will demonstrate how to change the brake fluid in the rim hydraulic brakes on a bicycle. These brakes were used on cross-country bikes in the past, but this technology has been replaced by disc brakes. However, bicycles with this type of brake are still being ridden and serviced in bike worshops.
This video will be of interest to cyclists and those interested in unusual mechanisms.
